“…They concluded that, the velocity increases with an increase in permeability of porous medium and it shows the reverse effect with an increase in magnetic and heat source parameters. Sinha et al (2017) examined MHD free convective flow through a porous medium past a vertical plate with ramped wall temperature. Their findings of the analysis showed that, an increase in permeability parameter, fluid velocity increases, whereas the velocity of the fluid decreases in the presence of magnetic field.…”

This research examines the impact of suction/injection and permeability of porous materials on a steady natural convection Couette flow of a viscous incompressible fluid passing through a vertical porous plate. The dimensionless governing momentum and energy equations were solved exactly. Graphs were plotted to check the impact of the governing flow parameters and a table was plotted for comparison of the results. It was found from the investigation that, the fluid injection (λ>0) increases the fluid velocity and temperature distributions while the magnetic field (M) retards the fluid velocity. It is also noteworthy to mention that the suction (λ>0) reduces the fluid velocity and temperature distributions in the channel. The velocity profile is observed to increase with increase in the permeability (K) of the materials.

In this paper, we analyze the effects of Hall current, radiation absorption and diffusion thermo on unsteady magnetohydromagnetic free convection flow of a viscous incompressible electrically conducting and chemically reacting second-grade fluid past an inclined porous plates in the presence of an aligned magnetic field, thermal radiation, and chemical reaction. An exact analytical solution of the governing equations for fluid velocity, fluid temperature, and species concentration subject to appropriate initial and boundary conditions is obtained using the perturbation technique. Expressions for shear stress, rate of heat transfer, and rate of mass transfer at the plate are derived. The numerical values of primary and secondary fluid velocities, fluid temperature and species concentration are displayed graphically, whereas those of shear stress and rate of mass transfer at the plate are presented in tabular form for various values of pertinent flow parameters. In addition, the skin friction on the boundary, the heat flux expressed in terms of the Nusselt number, and the rate of mass transfer

“…It is used, among other things, to explore the movement of water, oil, or natural gas in reservoirs in petroleum engineering, the filtration and purification process in chemical engineering, and the investigation of underground water in agricultural engineering. Numerous scholars have researched MHD flow in a porous media with different configurations because of the aforementioned applications; the current work likewise aims to add to this body of knowledge [15][16][17][18][19][20][21][22][23].…”

In this study, the numerical solutions for an exponentially stretching sheet with radiation effects, chemical reaction and a heat sink is obtained for the problem of MHD boundary layer flow. By using similarity transformation, the PDEs ruling system is converted into an ODEs system. The resulting nonlinear equations governing the flow problem are numerically solved by a successive linearization method (SLM) using MATLAB software. The significance of this paper is to show and compare the results of solving velocity, temperature, and concentration equations in the existence of changes through SLM for presenting it as appropriate and accurate method for solving nonlinear differential equations. Tables with the numerical data are created for comparison and displayed graphically. Analysis and studies of the effects of different parameters are conducted. The numerical values for the local skin friction coefficient, local Sherwood number, and local Nusselt number are tabulated and explained. The study demonstrates that different parameters have a substantial impact on the fluid flow profiles. It was noted that the concentration patterns were impacted by the reaction rate parameter. In addition, it was found that as the magnetic and radiation parameters increase in value, the local heat transfer rate at the surface decreases.
